IMPRO'VEMENT IN RINGS FOR SPINNING.

Specification forming part of Letters Patent No. 68,185, dated August 27, 1867.

To all whom it may concern: I

Be it known that I, HENRY G. HALL, of Fayetteville, Cumberland county, North Carolina, have invented a new anduseful Improvekment in Rings for Bing-Spinning; and I do hereby declare that the following is a full, clear, and exact description thereof, which will 'enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specificatiom-in which- Figure 1 is a bottom view of the inside ring, showing how the flange which sets in the collar or outside ring is formed eccentrically with the hole for the spindle and the circumference of the ring. Fig. 2 is a similar view of the collar or outer ring, showing how the ange which sets in the rail of the frame is formed eccentrically to the hole and its circumference. Fig. 3 is a central cross-section of both rings in positions on the rail, in the line .fr av', Fig. 4. Fig. 4 is a top view of the same.

Similar letters of reference indicate correspending parts.

This invention relates to an improvement in the construction of rings for ringspinning, whereby the inside ring may be exactly adjusted or centered concentrically with the spin- Ille.

The defects of vringspinning, arising from the difficulty of adjusting accurately the rin gl to the spindle, so that it shall run perfectly concentric, are well understood.

By `my improvement this difficulty is entirely overcome, so that the spindle shall always be adjusted exactly in the ycenter and run concentrically with the ring, and thus secure the desideratum in rin g-spinning of having a common center for the spindle-bobbin and traveler.

, The advantages of this improvement are very as there is no danger ofthe endsbeing cut down -by an imperfectly-adjusted traveler. It will allow the speed of the spindle to be increased to ten thousand turns per minute, or up to the point of vibration of the spindle, and will consequently spin more yarn in the same time and, iinally, theA spindle can be run with a light traveler, and both ring and traveler will wear and last longer.

A represents the rail; B, the bottom ring or collar, and (l the upper ring. Both rings have holes through their center, in the usual way; but the flange c on each ring is made eccentric to the inside and outside circumference of the ring, as shown in Figs. l and 2.

The eccentric-flange on the ring B its exactly' in the rail, and the iiange on the ring C iits exactly in the ring B.

When therings are in position on the rail, as shown in Fig. 3, either one or both may be turned around until the adjustment on the Aspindle is perfect, as will be manifest. The

rings are then secured in place by the two tightening-screws b e. The tightening-screw b passes through the side of the rail, and fast- Y ens the lower ring B by bearing against its eccentric-ange, and the other s-crew, c, passes through the collar of the lower ring B, and bears against the eccentric-flange of the inside ring C, thus firmly securing both rings with an exact and permanent adjustment to fittin g into the rail, and the latter with a simi- Y lar eccentric-iian ge tting within the ring B, when both are constructed to operate as set forth, and held in position by means of the Iset-screws b c, substantially as described, for

the purpose specified.
